Why You’ll Love This Kielbasa Sausage Cheesy Potato Casserole
You will love this Kielbasa Sausage Cheesy Potato Casserole because it uses simple pantry items and goes in one pan. It feels hearty and warm, the kind of meal that makes cold nights easier. The inside is creamy from the cheese and sauce, and the top turns crisp under the breadcrumbs. It keeps well for leftovers, and you can swap cheeses or vegetables to fit what you have. It is comfort food without stress.
What Kind of Kielbasa & Potatoes Should I Use?
Smoked pork kielbasa gives the best flavor, but beef or turkey kielbasa works if you want something lighter. Pre-cooked kielbasa is easiest because you just slice it and layer it. Russet potatoes bake soft and tender, while Yukon Gold stays a little firmer and creamy. Slice the potatoes thin so they cook all the way through. Even slices mean even cooking and no hard pieces in the middle.
Options for Substitutions
You can switch the kielbasa for turkey sausage or any smoked sausage you like. Try Colby Jack, sharp cheddar, or a mozzarella blend if you want a different melt. If you do not have cream of mushroom, use cream of chicken or cream of celery. Milk can be swapped for half-and-half or evaporated milk for more richness. For the topping, panko or crushed crackers will still give a crisp finish.
Ingredients for Kielbasa Sausage Cheesy Potato Casserole
Kielbasa sausage – sliced into rounds
Use smoked kielbasa for the best flavor. Pre-cooked works fastest, so you can slice and layer it right away.
Potatoes – peeled and thinly sliced
Thin slices help the potatoes cook evenly and stay tender. Russet or Yukon Gold both melt into the casserole nicely.
Onion – thinly sliced
Adds a soft, sweet flavor as it bakes. Spread it between layers so every bite has a little taste.
Cheddar cheese – shredded
Freshly shredded melts smoother and creamier than bagged cheese. Sharp or medium cheddar both work well here.
Cream of mushroom soup – forms the creamy base
Creates the rich sauce that holds the casserole together. It saves time and adds depth without extra steps.
Milk – thins the sauce
A splash of milk turns the soup into a pourable sauce. You can use more or less depending on how creamy you like it.
Butter – melted for richness
Melted butter blends into the sauce for extra flavor. It also helps the top brown beautifully.
Garlic powder – adds flavor
A small amount adds warmth without overpowering the dish. It balances the smoky sausage and creamy potatoes.
Salt & pepper – to taste
Season lightly as you layer so the flavor spreads through the whole casserole. Adjust based on the sausage you use.
Breadcrumbs – for crispy topping
Sprinkle on top for a golden crust. It gives that perfect contrast between creamy inside and crunchy top.
Fresh parsley – optional garnish
Adds a pop of color when serving. It makes the dish look fresh and homemade with almost no effort.
How to Make Kielbasa Sausage Cheesy Potato Casserole
Step 1: Prepare the Oven & Baking Dish
Preheat your oven to 375°F (190°C). Grease a 9×13 baking dish with non-stick spray or butter so nothing sticks. This gives the casserole a clean release after baking.
Step 2: Layer the Casserole
Place a layer of sliced potatoes on the bottom, then add kielbasa, onions, and cheese. Repeat the layers so everything is even and every bite has flavor. Think of it like building a cozy stack of comfort.
Step 3: Make the Creamy Sauce
In a bowl, whisk the cream of mushroom soup, milk, melted butter, garlic powder, salt, and pepper. It should look smooth and easy to pour. This sauce brings the whole casserole together.
Step 4: Pour Sauce & Cover
Pour the sauce over the layers, letting it sink down into the pan. Cover the dish tightly with foil so the potatoes steam and get soft while baking.
Step 5: Bake Until Tender
Bake covered for about 1 hour. The potatoes should feel tender when poked with a fork. If they are still firm, give them a little more time—every oven is different.
Step 6: Add Breadcrumb Topping
Remove the foil, sprinkle breadcrumbs over the top, and bake for 10–15 more minutes. The top should turn golden and crisp. If you like extra crunch, use the broiler for 1–2 minutes—but watch closely so it does not burn.
How Long to Cook Kielbasa Sausage Cheesy Potato Casserole
Bake this Kielbasa Sausage Cheesy Potato Casserole covered for about 1 hour at 375°F so the potatoes steam and soften. Then uncover and bake for 10–15 minutes to crisp the top and brown the breadcrumbs. The casserole is done when a fork slides easily into the potatoes and the edges look bubbly and golden. If the potatoes still feel firm, give it a little extra time—every oven is different.
Tips for Perfect Kielbasa Sausage Cheesy Potato Casserole
Slice the potatoes thin and even so they cook through at the same rate. Always bake covered first to trap steam and make the potatoes soft. Freshly shredded cheese melts smoother than pre-bagged and gives a creamier finish. Let the casserole rest for 5–10 minutes before serving so it sets and slices cleanly.
Watch Out for These Mistakes While Cooking
Avoid cutting the potatoes too thick or they will stay hard in the center. Don’t forget to season each layer or the flavor will taste flat. Baking uncovered too early can dry the dish out before the potatoes are ready. Make sure you have enough sauce to cover the ingredients so every bite is tender. If you broil at the end, watch closely so the breadcrumbs don’t burn.
What to Serve With Kielbasa Sausage Cheesy Potato Casserole
Simple Green Salad
A fresh green salad balances the richness of the casserole. A light vinaigrette cuts through the creaminess and keeps the meal feeling bright and complete.
Steamed Green Beans
Steamed green beans add color and a soft crunch on the side. A little butter, salt, and pepper is all they need to make the plate feel homestyle.
Roasted Brussels Sprouts
Roasted Brussels sprouts bring a deep, caramelized flavor that pairs well with smoky kielbasa. They add a hearty vegetable side without feeling heavy.
Garlic Bread or Dinner Rolls
Warm garlic bread or soft dinner rolls are great for soaking up the creamy sauce. They turn the meal into a cozy, no-fuss comfort dinner.
Butter Croissants
Flaky croissants make the whole meal feel special with almost no extra work. They add a buttery bite that matches the crispy breadcrumb topping.
Coleslaw
A chilled coleslaw gives a sweet and tangy contrast to the casserole. It keeps the meal from feeling too heavy and adds a refreshing bite.
Sautéed Cabbage
Sautéed cabbage is a classic partner for kielbasa. It’s simple, savory, and cooks quickly, turning the casserole into a full, old-fashioned dinner.
Storage & Reheating Instructions
Store leftovers in an airtight container in the fridge for 3–4 days, following USDA guidance for cooked meats and dairy dishes stored at 40°F or below. For longer storage, freeze the casserole (without the breadcrumb topping) for 2–3 months, then thaw overnight in the fridge to protect the potatoes from getting grainy.
To reheat, the oven works best—350°F for 15–20 minutes keeps the inside creamy and the top crisp; the microwave is fine for quick reheating, but add a pinch of breadcrumbs or broil for 1–2 minutes to bring back the crunch. Reheat uncovered so steam doesn’t soften the topping.

FAQs for Kielbasa Sausage Cheesy Potato Casserole
Can I make this casserole ahead of time?
Yes. Assemble the casserole, cover it, and refrigerate it for up to 24 hours before baking. Add the breadcrumbs right before it goes in the oven to keep the topping crisp.
Can I use raw sausage instead of kielbasa?
You can, but brown it first. Raw sausage releases more fat and moisture, so cooking it ahead prevents the casserole from getting soggy.
How do I know when the potatoes are done?
The potatoes are done when a fork slides in easily and the edges look bubbly. If they still feel firm, bake a little longer until fully tender.
Can I freeze this casserole?
Yes. Freeze before baking for best results, and skip the breadcrumbs until reheating. Thaw overnight in the fridge, then bake as usual.
What’s the best cheese for this recipe?
Sharp cheddar melts well and adds flavor, but Colby Jack or a cheddar-mozzarella mix also works. Freshly shredded cheese gives the smoothest, creamiest texture.
